Title: Vehicle steerable wheels toe-in control system
Inventor: YASUI YOSHIYUKI
IPC: B62D9/00
Filed: 1991-05-16
Abstract: A toe-in control mechanism 707 around a linking rod between a ball joint connected to a steerable wheel and a steering rod 704 comprises a piston and a fluid chamber. Increasing the fluid pressure in the chamber causes the piston to move in a direction that compresses a compressible element. Compression of the compressible element enables the linking rod, which is connected to the piston, to move in relation to the steering rod 704, and hence enables toe-in to be controlled. The supply of fluid pressure to vary the toe-in is electronically controlled in response to steering, sensed by a steering wheel angle sensor. Electronically-controlled power steering, responsive to yaw, is also described. <IMAGE>

Patent GB-2266366-A (GB)
Title: Light beam angle detection
Inventor: SEE CHUNG WAH
IPC: G01S17/06
Filed: 1992-04-16
Abstract: A system for measuring the angle of a beam of light is arranged so that a periodically varying pattern is formed on a photodetector (11), with a waveform property such as wavelength or phase of the pattern varying with the angle of the light. This may be done by creating interference between the light beam to be measured and a reference light beam having a fixed angle, or by forming a shadow on the detector array (11) of one or more masks (23, 25) having a periodically varying transmission characteristic. One convenient way of processing the output of the photodetector array is to perform a fast Fourier transform, obtain therefrom one or more spatial frequency components, and extract therefrom a part which provides a measure of the angle of the light beam. The use of a periodically varying pattern on the photodetector array (11) enables a substantial length of the array to be used in any particular measurement operation, and averages out individual performance differences between different elements of the photodetector array (11). The use of waveform properties enables convenient signal processing to be carried out, for example using well known fast Fourier transform techniques.

Title: Method and apparatus for detecting clogging of fluid filters
Inventor: MOUTON PIERRE CHARLES
IPC: B01D35/143
Filed: 1994-05-10
Abstract: Clogging of a fuel or oil filter 62 is an engine circuit is detected by monitoring a pressure difference which is corrected by a factor dependant on the flow through the filter, so that an alarm is given when the flow is less than the maximum. The direct pressure drop across the filter can be measured and then corrected electronically, e.g. by an engine speed factor. Alternatively, (Fig. 6) the pressure monitor 63 is subjected to pressure PC, measured in a venturi 65 upstream of the filter, which varies according to a power of the flow which is higher than that relating to the pressure P1 immediately upstream of the filter. In Fig. 8 the pressure monitor (89) is subject to the pressure in a centrifugal fuel pump whose speed depends on that of the engine. <IMAGE>
